What is it good for?

You can control up to 6 analogue LED stripes and 1 digital LED stripe (like WS2811) via DMX. You can dim the analogue channels individually and acces multiple effects for the digital one.

Inputs/Outputs

  • DMX In (3 pin XLR male)
  • DMX Out (3 pin XLR female)
  • Power in 12 V DC up to 95W
  • 6 analogue out 12V PWM dimmable
  • digital out + constant 12 V

Modes

You can use it in DMX mode or static function mode. Use the leftmost dip switch to choose between the modes:

  • ON: static function mode
  • OFF: DMX-mode.

There are currently two DMX modes (6 ch an 16 ch). The 6-channel-mode is meant to be used, when you only need the analogue channels.

0-10 OFF All lights are turned off - -
11-20 Analogue Style The strips acts like an analogue strip. Use the primary colors (ch.7 -ch.9) to mix the color and brightness -
21-255 Rising star A star with primary color shoots from start to end. Has a trail of secondary color behind it. Variable speed length of trail
